embodiment 1

[0048]FIG. 1 shows an air-course and a refrigerant circuit of a bathroom air-conditioner in accordance with the first embodiment of the present invention. As shown in FIG. 1, main unit 1 of the bathroom air-conditioner is placed under the roof of the bathroom, and includes intake port 3 and blowout port 4 open on its underside so that they communicate with bathroom 2. The intake port 3 and blowout port 4 open to bathroom 2 at different places from each other. A first end of evacuating duct 5 is connected to main unit 1, and a second end thereof communicates with outer blowout port 6. Circulating air-course 7 and ventilating air-course 8 are formed in main unit 1, and intake port 3 communicates with blowout port 4 through circulating air-course 7, and sintake port 3 communicates with evacuating duct 5 through ventilating air-course 8. Circulating fan 9 is placed in circulating air-course 7, and ventilating fan 10 is placed in ventilating air-course 8.

embodiment 2

[0091]A method of increasing an efficiency of energy is demonstrated hereinafter. This method increases an amount of heat to be collected during the heating operation. FIG. 7 shows schematically a sectional view of a bathroom air-conditioner in accordance with the second embodiment of the present invention.

[0092]The bathroom air-conditioner shown in FIG. 7 differs from that shown in FIG. 5 in the following points: Partition 52 is newly provided for separating circulating air-course 7 from ventilating air-course 8; Compressor 13, decompressing mechanism 15, and controller 54 are placed in ventilating air-course 8; Ventilating fan 10, heat absorber 24 are placed in this order from outer blowout port 6; and no flow-path switching valve is provided because the bathroom air-conditioner shown in FIG. 7 only implements the heating operation.

[0093]The bathroom air-conditioner shown in FIG. 7 comprises the following elements: shutter plate 53 for switching an air-course in ventilating air-co...

Abstract

A bathroom air-conditioner includes a refrigerant circuit in which a compressor, a radiator, a decompressing mechanism and a heat absorber are connected with one another through a pipe, a circulating air-course, and a ventilating air-course. In the circulating air-course, the radiator and a circulating fan for circulating the air of the bathroom are placed. In the ventilating air-course, the heat absorber and a ventilating fan for discharging the air from the bathroom to the outside are placed. The heat absorber makes the refrigerant absorb heat from the air of the bathroom, and the radiator makes the refrigerant dissipate heat to the air of the bathroom for heating the bathroom. During the heating of the bathroom, when a temperature of the bathroom becomes higher than a given temperature, a controller reduces an air-blow amount from the ventilating fan.

Description

TECHNICAL FIELD[0001]The present invention relates to a bathroom air-conditioner for air-conditioning a bathroom by using a heat pump.BACKGROUND ART[0002]A conventional bathroom air-conditioner using a heat pump has worked this way: A first heat exchanger of the heat pump radiates or absorbs heat to / from the air drawn from the outside of the bathroom, and then blows out the air into the bathroom. A second heat exchanger of the heat pump absorbs or radiates heat from / to air evacuated from the bathroom to the outdoors. The bathroom has been thus air-conditioned (refer to, e.g. Patent Document 1).[0003]The foregoing air-conditioner collects the heat from the air to be discharged from the bathroom to the outdoor, and gives heat to another air drawn from a place other than the bathroom, thereby air-conditioning the bathroom. A continuous operation of this air-conditioner sometimes generates a difference in enthalpy between the air drawn from a place other than the bathroom and the air in...
